Referring vnovv to thefdrawings;` Figs. 1i, Ziano 3 show a containerwhich -has'anf inlet Zfandfan outlet 7, andend Walls and 4-a.

-The-bo`ttom 3 ofthe container 'I has-'anlupvwardly projecting rib 5!)for seating anapertured horizontal baie 5. Av vertical apertured-ba'iile5 is disposed adjacent the inlet |11 toequal'zfthe pressure of the fluidentering into' the con einer and it also tends to equalize the rate'-of'v iibvvl of iuid passing through the Container Lf Thei-baiiies 5 and6 form a remevablebasket-- The'overl of the container I is secured tothe bottom 3 of the container I by a threaded rod 5l which threadablyengages an internally threaded boss member 52 in the bottom of containerI.

The end wall is spaced from the top Iii or" the container I, wherein theupper end 9 of the wall 4 forms a Weir which extends the width of thecontainer, the width oi' the weir 9 being several times the diameter ofthe outlet of the container I. The walls -a, II, II-a, and t form thefour sides of a spillway 8 leading from the weir 9 to the outlet 1.

The weir 9 preferably extends horizontally the entire width of thecontainer I, although it is not necessary thatgit extend the entirewidth oi' the container, so long as it is of substantially greater widththan the diameter of the outlet l. The height of the Weir 9 determinesthe static head of the pi'edominant liquid in the container in the firstinstance, and the head of liquid and solid matter in flotation in thesecond instance.

One of the advantages of having the Weir 9 of,

and liquid matter in flotation. The container I z.

has a depending baiile I2 spaced from the bottom 3 thereof forming apassage I2-a, leading upwardly to the weir 9 and the outlet 1. An airvent I3 is formed in the upper portion of the depending baille I2 bymeans of an oiset lip I5 on the baille I2, and a depending iiange I6which extends below the top of the Weir 9 a suicient distance to providea trap. The iiange I5 depends below the Weir 9 a suiiicient distance toprovide a seal, under normal circumstances, but provides a ready escapeof gases in the container I under abnormal circumstances. The lip I5extendsv approximately to the top cover It of the container I in orderthat there will be no over flow of liquid through the air vent I3.

In operation, matter in solid and fluid form from any source enters theinlet 2, and is dispersed by baffle 5, thereby equalizing the pressureof the fluid entering the inlet and tending tc make the velocity of theflow of uid passing through the container I more uniform. Solidparticles are retained by the apertured horizontal baiile 5 and thepredominant fluid passes through the passage |2-a, over the Weir 9, tothe spillway 8, and out through outlet 1. The fluid in the container Iis maintained in a more or less quiescent state, permitting theflotation of less dense matter of fluid or solid form on the surface ofthe predominant liquid. 'Ihe flow of fluid is continuous,

, until it/reaches the level of the Weir S, as shown by the dot and dashline A. The predominant uid maintains a level in the container withinvery narrow limits, regardless oi the rate of flow of the iiuid enteringinlet 2, inasmuch as the Weir 9 is of a width approximately the width ofthe container and increase of the head of the uid passing thereover issmall upon a multiple increase in the rate of flow. rIhis level will bemaintained, regardless of the amount of matter in liquid or solid form,floating on the surface of the level of the predominate liquid, withinreasonable limits.

A modified form of my invention is shown in Figures 4 and 5. In theillustration shown in Figures 4 and 5, all parts are made of fabricatedmaterial in contrast to the casting shown in Figs. 1, 2, and 3.Container S0 comprises side walls I9 and end walls 20 and a flangedbottom wall 2|. The end and side walls I9 and 20 have a marginal offsetmember 22 for receiving a gasket 23, utilized for seating the cover 24to seal the container 60. At the outlet end of the container SII, shownin Fig. 4, I provide a depending baille 25, spaced from the bottom 2i toform a passage 25-a. The upper portion of the baiile 25 is bent at rightangles to form a horizontal baie 26, extending transversely of thecontainer 50, the horizontal bale 26 being spaced from the top cover 24of the container 68. Horizontal baiiie 26 is attached to the end wall 20by welding or any other suitable means. A hand hole 30 is provided inthe horizontal baiile 25 for cleaning purposes. An internally threadedoutlet member 21, disposed in an aperture in the wall 20, forms anoutlet for container '69. An upwardly extending baille 28 has theupperend thereof spaced from the horizontal baiiie 26 to form a weir 9-a. Thebottom portion of the bafiie 23 is bent at right angles and secured tothe end wall 29 immediately beneath the outlet member 21. The Weir Sl-aextends horizontally cross the entire width of the container 5I)although it is only necessary that the width of the weir 9-a besubstantially greater than the diameter of the outlet. Depending venttubes 29 are disposed in the horizontal baille 26, to permit the escapeof air and gases from the container E9, the tubes 29 extending asuicient distance below the Weir S-a, to provide a trap for air in thecontainer 60 under normal conditions.

It will be evident that plastic or any other `form of material may beused to form a container with a Weir therein as herein described withoutdeparting from my invention.

It will be seen from the foregoing description that I have provided aninexpensive separator for liquid and solid matter ywhich maintains alevel of the lluid in theV separator within narrow limits under allcircumstances by the use of a weir, which prevents siphoning actionthrough the outlet, and which provides a means for permitting thepredominant uid in a separator to discharge under any circumstances. Y

I have further provided a separator which permits a greater amount ofiluid and solid matter in flotation because there is a minimum of changeof level of the predominant fluid in the container.

Various changes may be made in the specic embodiment of my inventionwithout departing from the spirit thereof or from the Yscope of theappended claims.
